The Head and the Heart’s 2009 debut album earned them lots of love in the Twin Cities, on the impetus of “Lost in My Mind” that was beloved by both 89.3 the Current and Cities 97. The coed folk-rock ensemble from Seattle — fiddler/singer Charity Rose Thielen spent time in the Twin Cities and her parents still live here — were organic and charming live. The group’s sophomore CD, “Let’s Be Still,” released last week, seems stuck in the ’70s, with shades of the Eagles, Fleetwood Mac and Crosby, Stills & Nash without the big-budget production. More modern vibes are experienced on the Mumford-ish but gorgeous “Gone” and the Coldplay-gone-acoustic “Fire/Fear.” Thao & the Get Down Stay Down and the Quiet Life open. (9 p.m. Sat & 8 p.m. Sun. First Avenue, sold-out.) Bream
